The possibility of using bacterial cellulose in particleboard technology

Abstract

The possibility of using bacterial cellulose in particleboard technology. The paper presents the results of the influence of bacterial cellulose multiplication on industrial pine particles (used in wood materials technology), and then the use of the obtained biomass in the production of particleboards with reduced density LP1 type. Based on previous preliminary studies it was determined that the most effective growth of bacterial cellulose occurs using 5% wood particles in the breeding mixture. Two series of particleboards were produced: control and containing bacterial cellulose. Selected mechanical properties of produced particleboards (modulus of rupture, modulus of elasticity and internal bond) and selected physical properties (swelling and water absorption after 2 and 24 hours of soaking in water) were determined in turn. The boards made with bacterial cellulose had lower MOR and MOE values. Swelling after 2 and 24 hours was lower for boards with bacterial cellulose. The presented tests allow to state that bacterial cellulose can be a potential raw material ingredient in the production of particleboard while meeting the minimum requirements of the technical specification for boards with reduced density LP1.
